NUT-LOCK.

Specification of Letters Patent.

Patented Jan. 5, 1909 Application flled. March 27, 1908. Serial No.423,600.

To all "whom it may concern:

Be it known that I, GEoRoE W. STUART, a citizen of the United States,residing at Newtowmin the county of Fairfield, State of Connecticut,have invented certain new and useful Improvements in Nut-Locks; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention has relation to nut locks generally, and particularly tothat kind or class of nut locks that are designed. to secure nuts onspindles, as for instance, the

nuts on the spindles of wagon axles or nuts on the spindles ofdoor-knobs.

It is the object of the invention to provide a nut lock that shall beefiicient, simple in construction, and capable of application toexisting structures as well as to new means that may be organized in themaking for the application of the improvement.

The invention consists of a spindle, bolt or cognate device, adapted tohave a nut turned. thereon and having a hole'or aperture formedtransversely therethrough and a nut also having a hole formedtransversely through it and each having sound, tough leather, ormaterial similar to leather, filled into said holes and a screw orscrews turned into said leather and ex ending through the said aperture,all as will be fully understood by those skilled in the art, in view ofthe annexed drawings, forming a part of this specification.

This invention will first be-described in detail in connection with thesaid drawings, and then be pointed out with particularity in thesubjoined claims.

Of the said drawings :-Figure 11 shows, in side elevation, the spindleof a vehicle axle provided withmy improvements. Fig. 2 is a longitudinalsectional view of the same. Fig. 3 is a sectional view of a door spindleand knob equippedwith my improvements. I

Similar figures of reference designate similar parts or features, as thecase may be, wherever they occur.

. In the form of the device shown in Fig. 3 there is provided a doorknob 11 arranged to fit over the spindle 6, the remainder of the membersbeing substantially the same as those shown in F igs. 1 and 2 with theexception that in this form there isno threaded end or threaded recessbut the knob is held upon the spindle by the frictional resistance ofthe leather in the slots and the screw 9. The knob can thus bepositioned accurately in desired relation to the spindle.

I have instanced a vehicle axle and the spindle of a door-knob as meansto which my invention may be applied, merely because the said means aredevices with which the public is universally familiar, and not becauseof any limitation in the use of the invention.

In the form of the device shown in Figs. 1 and 2, I form an aperture 5of any desired size and shape through the externally screwthreaded partor device 6, that is adapted to receive an internally screw-threaded not7 thereon, and also make an aperture 8 transversely through the nut, sothat at some point in turning up the nut the apertures in the twoseparate parts or members will be brought into registering position. Thetwo apertures made as aforesaid are filled with tough leather or similarsubstance, packed in very firmly.

When the nut 7 is turned up quite tight on the spindle 6, or other partdesigned to receive the nut, and the holes are brought into properregistering position a screw 9 with a sharp thread and preferably thoughnot necessarily provided with a sharp gunlet point 10, is turned intothe said leather in said holes in a line transversely to the axis of thespindle, bolt, or other instrumentality on which the nut 7 is turned. Bythis means the nut will be securely held against turning back orbecoming loose not only by the screw but by what may be mentioned as thesurplus leather crowding and choking the screw threads in proximity tothe operation.

Should it be desired to remove the locked nut, this can be done byturning out the locking screw 9 with a screw-driver when the nut can beturned off with a wrench or spanner.

I am aware that in door-spindles, and some other devices, it has beenproposed to turn a screw into a screw-threaded hole formed transverselythrough a knot or member and spindle, but I do not know of leather orsimilar substance having been combined therewith as proposed by me in myinvention.

The hole made through the spindle or cognate device may be oblong aswell as round. In the former instance, it will allow adjustment, thatis, the nut may be turned up further in the former than in the lattercase, and yet leave room for the shank of the screw. In the latterexample there will be but one point at which the leather-filled holeswill be brought into registering position.

Other variations may be made in the form and arrangement of parts withinthe scope of mechanical skill without departing from the general natureor spirit of the invention.

What is claimed is: I 1. In a nut lock, an externally screwthreaded partor member, and a nut adapted to be turned thereon, the said part ormemher and nut having holes formed transversely therethrough, toughfibrous material filling said holes, combined with a sharp threadedscrew turned into said leather through the said holes. 2. In a threadedpart or member, and a nut adapted to be turned thereon, the said part ormemnut lock, an externally screwher and nut having holes formedtransversely therethrough, the hole formed through the first-mentionedpart or member being oblong in form, tough fibrous material filling saidholes, combined with a sharp threaded screw turned into said fibrousmaterial and through the said holes.

3. The combination with two members fitted one within the other, theinner member having a recess extending therethrough ad jacent to theouter member, terial filling in said recess, and a screw passed throughthe outer member and engaged in the fibrous material filling, wherebythe tWo members are held against disconnection.

In testimony whei eo i, T afiix my signature, in presence of twowitnesses.
